Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer facility using movable bodies, which is used for densely moving a group of movable bodies on a fixed path on the floor side.

[0002]

2. Description of the Related Art Conventionally, as a means for moving a non-driving type movable body on a fixed path, there has been provided a structure disclosed in, for example, Japanese Patent Laid-Open No. 2-209309. This conventional configuration is
The movable body transporting device is provided on the upper side of a fixed path on which the movable body can travel freely, and the braking device is provided on the lower side. The movable body transporting device is composed of a pair of left and right feed rollers that can come into contact with the side surface of the movable body, and a rotation drive device that interlocks with these feed rollers. In addition, the brake device, a pair of left and right brake rollers that can freely contact the side surface of the movable body,
It is composed of a torque motor that applies reverse feed rotational force to these brake rollers.

According to such a conventional structure, a large propulsive force is applied to the movable body by forcibly rotating both feed rollers, which are in contact with both side surfaces of the movable body, by the rotation drive device. The movable body can be moved on a fixed path.
At this time, the movable body is moved by pushing the movable body group that is preceding and stopped.

On the lower side of the fixed path, since the brake roller which is rotated in the reverse direction is in contact with both side surfaces of the movable body, a propulsive force in the reverse conveyance direction acts on the movable body, and the feed rotation is performed here. Since the force is larger than the reverse feed rotational force, the brake roller is rotated to the feed rotation side according to the difference. As a result, the lower movable body is moved in a state of being subjected to the braking action, and therefore the movable body group is moved in a dense rearward pushing state without forming a gap between the front and rear ends.

[0005]

According to the above-mentioned conventional structure, since the movable body is a rigid (integrated) trolley type movable body, for example, in the case of a movable body for handling a long transported object, the whole is Larger and heavier.

When the feeding device acts on the movable body,
This can be done without any trouble when the fixed route is straight, but the curved route portion (turn route portion, etc.) where the fixed route is curved in a plan view, or the curved route portion that moves from the horizontal route portion to the ascending route in a side view, In a curved path part that moves from a horizontal path part to a descending path, the relative angle formed by the front and rear movable bodies becomes an acute angle, and the boosting cannot be performed smoothly. Become. Therefore, it cannot be used for a fixed route having such a curved route portion.

Incidentally, as shown in, for example, Japanese Patent Laid-Open No. 61-166768, there is also provided a structure in which a plurality of carriers (movable bodies) are connected and rearwardly moved, but in this case, in a curved path. Since the pushing is performed by the abutting of the cushioning members provided on the side edges of the wide carrier, the carrier is inclined by the displaced pushing force, so that the stable movement cannot be performed in the curved path.

The object of the present invention is to make the main body of the movable body slender and compact, and to smoothly and securely move the movable body group in a dense (train-like) manner even in a fixed route having a curved route portion. The point is to provide a transfer facility using a movable body that can be stably and stably.

In order to achieve the above-mentioned object, the transport facility using a movable body according to the first aspect of the present invention comprises a movable body main body, which is supported and guided by rails and is movable on a fixed path, and a connecting device. It is formed by a plurality of frame bodies that are relatively rotatably connected to each other via the side surfaces of these frame bodies as passive surfaces, and at least one of the frame bodies is provided with an object support portion and a rail. In addition to providing a pair of guided devices supported and guided on the other side, the remaining frame body is provided with a guided device on the free end side, and a feed roller having a feed roller capable of contacting the passive surface is provided in the fixed path. A device is provided.

In the transfer facility using movable bodies according to the second aspect of the present invention, the front and rear ends of the main body are formed as abutting portions. Further, in the transfer facility using movable bodies according to the third aspect of the present invention, the engaging portion is formed on one of the front and rear ends of the main body, and the engaged portion is formed on the other end.

In the transfer facility using movable bodies according to the fourth aspect of the present invention, the main body is composed of three frame bodies, and the transported object support portion is provided on the intermediate frame body.

[0012]

According to the configuration of the first aspect of the invention described above, only the object supporting portion may have a shape adapted to the object to be conveyed, and the main body can be formed elongated and compact. Then, with the movable body facing the feeding device, the feed roller that is forcibly rotating is brought into contact with the passive surface, so that the feeding device applies a propulsive force to the movable body. The body can move on a fixed path. In that case, the main body of each movable body, that is, each frame body can be moved as a linear posture in a plan view and a side view in the straight path portion of the constant path, and in the left and right or up and down curved path portions, each frame body is moved. Can be moved in a bent posture along a curve at the connecting device.

According to the structure of the second aspect of the invention described above, in the linear path portion, since each frame body has a linear posture in plan view and side view, the frame body is located in the central portion in the width direction of the preceding movable body. The abutting portion of the succeeding movable body comes into contact with the abutting portion from directly behind, so that the pushing movement can be smoothly and reliably performed thereafter. In addition, in the left and right or up and down curved path portions, since each frame body is pushed and moved along the curve in a bent posture, the relative angle between the rear frame body of the preceding movable body and the front frame body of the succeeding movable body is formed. Can be made an obtuse angle, and the abutting portion of the succeeding movable body comes into contact with the abutting portion located at the center portion in the width direction of the preceding movable body at an obtuse angle, and the pushing movement can be smoothly and reliably performed thereafter.

Further, according to the structure of the third aspect of the present invention described above, the feeding device acts on the preceding movable body in a state where the movable body group is connected in a train shape by engaging the engaged portion with the engaged portion. Then, the subsequent movable body group can be moved by pulling.

According to the configuration of the fourth invention described above,
By supporting the guided object with the intermediate frame body and supporting and guiding the guided devices provided on the front and rear frame bodies, the movable body can always be stably moved.

A feeding device 40 that applies a traveling force to the movable body 10 by acting on the passive surface 15 is provided at a predetermined position on each of the linear path portions 5a. As shown in FIGS. 6 and 7, the feeding device 40 has a vertical axis 42 provided upright on a base body 41 continuous from the machine frame 2 on the outer side of the rail 3. The vertical axis 42 has a bearing 43.
The support member 44 is swingably mounted around the vertical axis 45 via the.

A rotation drive device (motor or the like) 46 is arranged on the support member 44, and a feed roller made of, for example, urethane is attached to an output shaft 48 taken out upward from a speed reducer 47 interlocked with the rotation drive device 46. 49 is fixed. The rotation driving device 46 applies the feed rotational force A to the feed roller 49. The support member 44 integrally has a bracket 50 extending forward, and the support member 44 is provided between the bracket 50 and the base body 41.
A cylinder device 51 for swinging is provided.

Therefore, by operating the cylinder device 51, the support member 44 can be swung around the longitudinal axis 45, and the feed roller 49 can be moved toward and away from the one passive surface 15. At that time, in order to regulate the position approaching the maximum, a stopper body 52 is continuously provided from the support member 44, and a stopper body 53 with which the stopper body 52 can come into contact is positionally adjusted to the base body 41. It is provided freely. A stationary roller 54, which is opposed to the feed roller 49 and is in contact with the other passive surface 15, is provided via a vertical axis 55 so as to freely rotate.

As shown in FIG. 9, the linear path portion 5a
In other predetermined places of the movable body 10 acting on the passive surface 15
A braking device 60 that applies a braking force to the vehicle is provided. Further, a feeding / feeding device 65 is provided between the feeding device 40 and the braking device 60. The arrangement pattern of each device 40, 60, 65 may be variously changed, and the braking device 60 and the sending-in / out device 65 may be partially or entirely omitted.

The braking device 60 has a structure similar to that of the feeding device 40, is capable of abutting and separating from one side of the passive surface 15 of the movable body 10 from the side, and is made of, for example, urethane braking roller 61. A reverse rotation drive device (torque motor) 62 that interlocks with the braking roller 61 and applies a reverse feed rotational force B to the braking roller 61, and a receiving roller that allows the other passive surface 15 of the movable body 10 to come into contact with each other. It is composed of 63 etc. The reverse feed rotational force B by the reverse rotation drive device 62 is set to be smaller than the feed rotational force A of the rotation drive device 46. Further, the feed-in / feed-out device 65 has the same structure as the feed device 30.

Next, in the above-described first embodiment, the movable body 10
The moving work will be described. For example, infeed device
The movable body 10 sent out by operating the 65 in the same manner as the later-described feeder 40 is moved in a state in which the feeder 40 side is in a receiving posture. At this time, the fed movable body 10 is attached to the contact surface 39 at the rear end of the rearmost movable body 10 of the movable body 10 group located on the fixed path 5 in the form of a dense train.
The contact surface (38) at the front end of the movable body (10) comes into contact with the movable body (10), and the movable body group (10) is moved by the feeding force of the feeding and feeding device (65).

The feeding by the feeding / feeding device 65 is stopped when the front end of the corresponding movable body 10 enters the feeding device 40. At this time, the cylinder device 51 of the feeding device 40 is extended to swing the supporting member 44 outward about the longitudinal axis 45, so that the feeding roller 49 is moved from the passive surface 15 as shown by the phantom line in FIG. It is separated. Therefore, the movable body 10 can be moved (loaded) without any trouble.

After that, the feed roller 49 is moved closer to the passive surface 15 by the action opposite to that described above so as to come into pressure contact with one of the passive surfaces 15 and the other passive surface 15 is brought into contact with the stationary roller 54. As a result, the front frame body 12 is sandwiched by the rollers 49 and 54. At this time, the feed roller 49 is rotationally driven by the rotary drive device 46. Therefore, by forcing the feed roller 49 which is forcibly rotated into contact with the passive surface 15, the moving force is given to the movable body 10 by the feed rotation force A thereof, so that the movable body 10 can move in a desired direction on the fixed path 5. It moves at a speed and pushes the movable body group 10 located in the fixed route 5 in the form of a dense train.

At the time of such movement, the guided devices 30, 3
1 and 32 are supported and guided by the rail 3 via the supported rollers 36, and the guided rollers 37 abut on the guide members 4 which are vertically distributed, so that the guides without rattling and the movable body 10 Sideways fall prevention is performed.

The feed amount of the movable body 10 by the above-mentioned feed device 40 is detected by an encoder or the like, and when a predetermined feed amount is detected, the feed roller 49 is separated and the moving work is stopped. The movable body 10 moving on the fixed path 5 is braked by the braking device 60. That is, when the movement of the movable body 10 by the feeding device 40 is stopped, the cylinder device in the braking device 60 is contracted, and the braking roller 61 is separated. Then, in synchronism with the feeding movement of the feeding device 40, the braking roller 61 is moved closer to and brought into pressure contact with the passive surface 15 by the action opposite to that described above. At this time, the braking roller 61 is on the opposite side of the feeding roller 49. It is driven to rotate.

That is, the braking roller 61 is forcedly rotated in the opposite direction by the driving of the reverse rotation drive device 62. Therefore, when the braking roller 61 that is forcedly rotated is brought into pressure contact with the passive surface 15, the reverse feed rotational force B acts on the movable body 10 in the reverse movement direction. Since it is larger than the rotational force B, the braking roller 61 is rotated toward the feed rotation side according to the difference, and the load at that time is absorbed by the torque motor.

As a result, the movable body 10 corresponding to the lower braking device 60 is moved in a state of being subjected to the braking action. Therefore, a plurality of movable bodies 10 are provided between the feeding device 40 and the braking device 60. However, they are densely aligned in the rearward pushing state without forming a gap between the front and rear ends thereof. The braking action of the braking device 60 is stopped before and after the movement of the feeding device 40 is stopped.

As described above, while the movable body 10 is intermittently moving on the fixed path 5 or while the movable body 10 is stopped, the worker can perform various works on the transported object 29. It should be noted that the movable body 10 pushed out from the braking device 60 by the above-described backward pushing reaches the feeding-in / feeding-out device 65.

When the movable body 10 is moved by the above-described feeding device 40, the feeding roller 49 is moved to the passive surface 15 of the front frame body 12.
To the passive surface 15 of the intermediate frame body 13 and the passive surface 15 of the rear frame body 14 sequentially.

At this time, the feed roller 49 is attached to the front frame body.
When acting on 12, the intermediate frame body 13 and the rear frame body 14 are pulled and moved through the connecting device 20, and when acting on the intermediate frame body 13, the front frame body 12 is connecting device. While being pushed and moved via 20, the rear frame body 14 is pulled and moved via the coupling device 20,

Since the contact portion 38 comes into contact with the contact portion 39 from directly behind, the pushing movement can be smoothly and reliably performed.

In the curved path portion 5b, each frame body is
12, 13, 14 are pushed and moved in a bent posture along the curve at the connecting device 20 in plan view. Thereby, in a plan view, the relative angle Θ formed by the rear frame body 14 of the preceding movable body 10 and the front frame body 12 of the following movable body 10 becomes an obtuse angle, and the contact portion 38 with respect to the contact portion 38.
